From sci-fi to reality: Researchers realise quantum teleportation using tech (cordis.europa.eu)

> extremely cold temperatures (267 °C)

Sorry?

(I have a feeling someone meant Kelvin, though 267 K is hardly ‘extremely cold’ either…)

Anyone better at physics than me willing to explain how this does not break general relativity ? I might be missing the point of the experiment completely to be fair

Why does the title have part of it omitted? It completely changes the meaning.

Now it reads as "someone built something using tools". What tools? Why is using tools newsworthy?
